TECHNICAL FIELD

The invention relates to the technical field of drainer, and in particular relate to a quick-assembly deodorant drainer for washbasin.

BACKGROUND

In daily life, drainer is one kind of the indispensable sanitary wares, which can be installed in a drainage system such as a sink, a washbasin, a mop pool or the like. The existing drainers are divided into common drainers and table-controlled drainers. The common drainers include bouncing type, pressing type, etc., wherein a common drainer is directly operated when the water in a washbasin with the drainer is drained, thus a hand will have to reach into the dirty water for operation, thereby leading to disadvantages of occupancy of large space and inconvenient use, and the hand may be very easily injured especially in winter. Moreover, an existing table-controlled drainer of bouncing type has many components, the assembly for it is complicated, and the disassembly and replacement is troublesome.

In view of the above, the applicant has developed and designed the invention through deep conception and active research, improvement and trial, considering the many defects and inconveniences caused by imperfect structural design of the above-mentioned drainer and washbasin.

The outer side wall of the lower end of the mounting portion is provided with a first external thread, the inner side wall of the upper end of the connecting portion is provided with a first internal thread that mates with the first external thread, and the lower end of the mounting portion and the upper end of the connecting portion are connected through the first external thread and the first internal thread.

The lower end of the mounting portion is provided with a first connection sealing nut, and the first connection sealing nut is used for sealing a position where the lower end of the mounting portion is coupled with the upper end of the connecting portion.

The convex portion is integrally formed with the cylinder, and the top end of the convex portion is located below the top end of the cylinder.

The sealing cover is integrally formed with the fixed shaft, the sealing cover is mated with the lower end opening of the cylinder in a sealing manner, and the upper end of the fixed shaft is threadedly connected with a fixed portion disposed at the inner top portion of the sleeve.

The outer diameter of the fixed shaft is smaller than the inner diameter of the through hole in the convex portion, and the fixed shaft moves up and down along the through hole of the convex portion.

The outer diameter of the convex portion is smaller than the inner diameter of the sleeve, and at the same time when the fixed shaft moves up and down along the through hole of the convex portion, the sleeve moves up and down along the convex portion.

The lower end of the connecting portion is provided with a second connection sealing nut, and the second connection sealing nut is used for sealing the connection position of the connecting portion and the sewer pipe.

The embodiment of the invention has the following advantages: the quick-assembly deodorant drainer for washbasin provided by the embodiment of the invention has the characteristics of simple structure, convenient installation and maintenance, and the design of integral forming eliminates the water leakage problem caused by improper installation at the interface. At the same time, it also has the characteristics of odor-resistant, anti-overflow and anti-clogging. Moreover, by using the deodorant anti-overflow device with the above design, when water flows through the mounting portion into the connecting portion, the gravity of the water makes the sleeve move downward along the convex portion, and the compression spring sleeved over the outer side wall of the convex portion is compressed downward. Meanwhile, the fixed shaft disposed in the sleeve moves downward with the sleeve, so that the sealing cover fixedly connected at the bottom of the fixed shaft is separated from the water-flow hole, and the water flows into the sewer pipe and then flows out. When the drainer is covered and no water flows through, the compression spring bounces the sleeve upward along the convex portion, and the fixed shaft moves upward together with the sleeve, thereby driving the sealing cover to move upward until it abuts against the bottom end of the cylinder so that the water-flow hole is sealed. As such, it is difficult for the odor and sewage in the sewer to enter the cylinder, thereby achieving the purpose of deodorization and anti-overflow.
